ERNEST H. SWIFT, OF HARTFORD, CONNECTICUT.

PACKAGE-ROLL OF METALLIC LEAF.

Specification of Letters Patent.

Application filed February 25, 1914. Serial No. 821,024.

To all whom it may concern Be it known that I, ERNEST H. SWIFT, acitizen of the United States, residing at Hartford, in the county ofHartford, State of Connecticut, have invented a new and ImprovedPackage-Roll of Metallic Leaf, of which the following is aspecification.

My invention relates to packages of metallic leaf that are wound upon acore, the metallic leaf being placed upon a backing or base of paper orsimilar material before the winding takes place, and an object of myinvention, among others, is to provide for such a roll a core that maybe separated by the use of an instrument that will not waste or cut awayany of the material.

One form of package roll embodying my invention and in the constructionand use of which the objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which Figure 1is a view in side elevation of a package roll wound upon my improvedcore. Fig. 2 is an end view of the same. Fig. 3 is a detail side view ofa separated disk. Fig. 4 is a view partially in lengthwise sectionthrough the core showing its action under the influence of the cuttingtool.

By the use of my invention described herein I am enabled to produce apackage roll of metallic leaf having a core formed of extreme rigidityand strength, which is a desirable feature of wooden cores heretoforeused, but which wooden cores were objectionable from the fact that theycould not be out without a waste of the material upon them. My improvedpackage, however, possesses the advantage that the core may be outwithout a waste of material and in a manner to produce a package havingan extremely finished appearance.

In the accompanying drawings the numeral 5 indicates the core of myimproved package roll, this core being formed of a single piece of paperspirally wound, the paper being of proper width to produce a package 7of the required length, this core being wound upon a quill 6 of paper orsimilar material. The paper is tightly wound to produce a core of therequired thickness to possess the requisite qualities as to rigidity,the several wraps 0r layers of the paper being free from any adherentmaterial, and the end of the paper strip being secured in any desiredmanner. In fact I contemplate cases where the end may not be secured.

The metallic leaf, with its base or backing of paper or like material iswound upon this core to the desired extent, and a pack age is thusproduced which may be easily separated into comparatively short lengths8 by the use of a knife, the package being rotated in this operation andthe knife cutting entirely through the metallicleaf and the core, thusproducing a package having extremely smooth sides. The formation of thecore is such that it will not break and crack, as will a wooden core, ifan attempt be made to cut it, but the several layers of the paper of thecore will slide one upon another to produce a gash of a width to permitready entrance of the knife blade. That is, the superposed layers ofpaper in the core readily yield to the action of the knife and permit itto easily enter the material and sever the short lengths from the mainroll. The form that will be assumed by the core of the disk beingsevered is shown i Fig. 4 of the drawing.

While I have shown and described herein a satisfactory means of carryingmy invention into effect, this may be changed to a greater or lesserextent without departing from the spirit and intent of the invention.

I claim 1. A package roll of metallic leaf including a core separatelyformed from paper tightly wound into a number of superposed layers tothe required thickness, said layers being slidable one upon another.

2. A package roll of metallic leaf including a core separately formedfrom paper of a width equal to the length of the core, said paper beingtightly wound into a number of superposed layers to produce a core ofthe required thickness, said layers being slidable one upon another.
